Day 2 of being home sick...blah! It was killing me, having some goodies delivered yesterday and today, still feeling like **** and it being in the low 50s. I was optimistic that I'd get started on this project tomorrow, so after lunch, about 12:30pm, I decided to go out and hit the flange bolts with some PB Blaster. At first that was all I was going to do today. But 20 minutes went by and I said screw it, sick or not, my exhaust is being ripped off and the 4" Flo-Pro is getting installed! I went out and started turning a wrench at 1pm.
The bolts from both the front and rear flanges came off easy (perks of having a newer truck that the salt hasn't got to yet). I had just ordered the Lisle exhaust hanger removal tool yesterday from Amazon but it slipped my mind while I began disassembling the stock exhaust. In the process of removing the sensor plugs from the ***, I realized I didn't have that tool yet. Oh well, I'll figure something out.
So after disconnecting all the EGT sensors, Oxygen Sensors and DEF Injection, it was time to tackle the exhaust hangers. I did hit them with PB Blaster when I hit the flange bolts so I was hoping that would with the removal. With a pair of channel locks, they actually came off very easily. I guess I can return the Lisle tool when it arrives.
So I then wrestled the 80lb filter out from under the truck. I was able to remove the back section of the stock exhaust no problem without lowering the spare tire like I have read must be done.
Anyhow, on to figuring out and piecing the new Flo-Pro together.
Bolted the front flange section first, as the instructions state. Which by the way, I thought were not provided, but it was slipped in between a cardboard tab of the box. Sneaky.
From there, it was pretty straight forward. Install pieces loosely from front to back. Left all the clamps loose until it was positioned correctly. Once I liked the positioning, started tightening everything up from the back to the front.
In no time at all, I had the exhaust installed. It was 3:15pm. Only took me a little over 2 hours to rip the old exhaust out and install the new one.
From there, I moved up to the engine bay and just unplugged the 3 EGR plugs for the time being. I'll block the EGR off tomorrow along with sealing and bagging all the plugs under the truck.
Loaded the Tyrant Street Tune and fired it up. Yeah! I have both the diesel sound and smell back!!! Sounds good and it's really not bad inside the cab. Not nearly as loud as my 6.0 was, that's for sure. Took her for a spin around the country block. Laid into her...man she can go now!
Super excited for the NL Stage 2 Intake now to arrive so I can pair it all together.
I did take before and after videos that I'm trying to load to Youtube and then put on here. I'll post them when they are done loading.
I was getting 14mpg (gauge) before the removal. I'll see how that changes over the next week of driving.
